Thanks for the info all. I did find PPI's Handbook of PE pipe but did not see anything expressly prohibiting nor giving the practice the thumbs up. Unfortunately the client has shelved the project for now and stopped all contract work on it! I appreciate the swift feedback from everyone.
Can anyone recommend good sources of information regarding codes or standards for HDPE pipe and concrete foundations? A current project of mine involves piping fluid below grade from an outdoor storage tank and coming above grade indoors. The client has requested the use of HDPE pipe and wants...
I am currently trying to determine the adequacy of an existing vent in a tank for a pressure relief scenario. Is there a particular equation or calculation to verify what size vent is needed?
I have looked through API 2000, NFPA 30 and Crane TP 410 (the most difficult to interpret) and thus...
Thank you for the insight. I will consult with the operations crew. I am not sure if it is a client requirement or what? I have recently been added to this project group and don't have the full details.
The reason I am doing this is to get an idea of what velocities will be seen at some level flow sensors installed at these vent lines. I am under the impression that this will aid the procurement and electrical folks in determining what flow switches they need. You are correct-I did not draw...
On my first attempt I did get a velocity that was way too high (around 600 m/s!) and knew I did something wrong or made a faulty assumption. A second attempt provided more believable results but I am still concerned about some of my assumptions and the way I simplified things on my model. I...
I have a piping system consisting of a pig launcher with a fill line flowing into it and a vent line flowing out of it. The 2" diameter fill line pulls crude off a mainline operating at 1017.1 psi and a flow rate of 633 Kbpd. The crude flows from the mainline to a pig launcher via the fill...
